Reason for the 21 suggestion here, is that it WORKS WELL in an 88", and as we all know how things go....the customer wants more.....then once bored to 98", and say some mild head work.....it still works, only better.

I am looking at upgrading a similar 03 FX bike with a carb and it will stay at 88 inches looking at the 21's also..

Ok, so I'm seriously considering the Andrews 21s now. Is there any reason why the S&s 509 would be better than the Andrews 21?

We have also used their 574's in a few builds and from a numbers/feel stance there are comparable cams that perform much better...

The 509 has an 18* intake close to boost CCP and corrected CR which is why it is a good choice for a Stage 1 88" motor; it was designed for that application.

Default More Torque

My ride is a 2016 Streetglide and it already has V and H dresser duals (cat converter gone) high flow intake and V and H tuner. Any ideas on a cam change that would give a significant boost to low - mid range torque without any top end work?
